LongPredicate
public interface LongPredicate
| java.util.function.LongPredicate |
Represents a predicate (boolean-valued function) of one long-valued argument. This is the long-consuming primitive type specialization of Predicate.
This is a functional interface whose functional method is test(long).

Summary
Public methods | |
|---|---|
default LongPredicate | and(LongPredicate other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. |
default LongPredicate | negate() Returns a predicate that represents the logical negation of this predicate. |
default LongPredicate | or(LongPredicate other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. |
abstract boolean | test(long value) Evaluates this predicate on the given argument. |
Public methods
and
public LongPredicate and (LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.
Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.
| Parameters | |
|---|---|
other | LongPredicate: a predicate that will be logically-ANDed with this predicate |
| Returns | |
|---|---|
LongPredicate | a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException | if other is null |
negate
public LongPredicate negate ()
Returns a predicate that represents the logical negation of this predicate.
| Returns | |
|---|---|
LongPredicate | a predicate that represents the logical negation of this predicate |
or
public LongPredicate or (LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.
Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.
| Parameters | |
|---|---|
other | LongPredicate: a predicate that will be logically-ORed with this predicate |
| Returns | |
|---|---|
LongPredicate | a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException | if other is null |
test
public abstract boolean test (long value)
Evaluates this predicate on the given argument.
| Parameters | |
|---|---|
value | long: the input argument |
| Returns | |
|---|---|
boolean | true if the input argument matches the predicate, otherwise false |
